TILE-CUTTING- TABLE.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed June 8, 1910. Serial No. 565,822.

To all whom 'it may concern:

Be it known that I, MAX MUELLER, a subject of the Emperor of Germany, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Tile-Cutting Tables, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in tile cutting tables, the object of my inven tion being to construct a tile cutting machine in which the operation of cutting the tile is continuous, that is can be accomplished without stopping the tile forming machine.

A further object of my invention is to construct a machine for continuously cutting tile and the like without the employment of an extraneous driving mechanism, the cutting members being driven solely by the weight and pressure of the tile from the tile forming machine.

For the above purposes my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which:

Figure 1 is an elevation of the complete tile cutting machine, a portion of the tile forming machine and the product therefrom being shown in dotted lines; Fig. 2 is a plan of the complete tile cutting machine;

' Fig. 3 is a transverse, sectional elevation of j the machme taken on the llne 3 3 of Fig.

1; Fig.l 4 is a view illustrating the cutting member in a position after a cut has been made; Fig. 5 is an enlarged, detail elevation of the cutting fra-ine support taken approximately on the line 5--5 of Fig. 3; Fig. 6 a sectional elevation taken on the line 6-6 of Fig. 5; Fig. 7 is a sectional elevation illustrating the cams for operating the cutting members taken on the line 7 -7 of Fig. 3; Fig. S is an enlarged, detail, sectional elevation illustrating the means whereby the cutting membersl are caused to move with the tile during the time a cut is being made, taken on the line 8-8 of Fig. 2; Fig. 9 is an enlarged elevation partly in sect-ion illustrating the cam which disconnects the cutting members from the conveyer after a cut has been made and Fig. l0 is a detail,

right hand elevation illustrating a portion of the means for returning the cutting members to their initial positions.

Referring by numerals to the accompanying drawings: 1-1 designate the end frame members which are connected by the track ways 2, the track ways being preferably constructed of angle iron having horizontal portions between the frame members 1 which are connected with the rounded end portions 3, the portions 2 and 3 forming a continuous track way. Arranged beneath the lowermost track way 2 is a track way 4. Arranged for travel on the track way is an endless conveyer which is composed of the links 5, each end of each link terminating in a down-turned perforated extension 6.

7 designates shafts which are extended through the extensions 6 of the links for pivotally connecting the links in pairs and for the support of the rollers 8, which rollers are designed for travel upon the track ways. Between each pair of links is a tile carrying block 9 the upper face of each of which is shaped to conform with the articles to be cut, as shown, the blocks each are provided with trough-shaped depressions 10. This form of conveyer block is designed for use in the formation of hollow drain tile as indicated by dotted lines in Figs. 1, 3 and 4. As shown, each of the blocks is of a length slightly less than the length of the links so that there will be a space between each pair of blocks for the operation of the tile cutting device.y

11 designates a shaft which is loosely mounted on the left hand side of the machine in bearings formed adjacent the tops of the frame members 1. Carried by the shaft 11 are the cross-fittings 12 secured to move with the shaft by the set screws 13. Carried by each cross-fitting is a bow-shaped frame 141, the frames being connected by the cross-rods 15. At the outer free end of each frame there is an eye 16 and secured to each of the eyes 1G there is a wire 17. In the frame members diametrically opposite the eyes 16 are the bolts 18 having hooks at their inner ends to which the wires 17 are secured. The opposite or outer ends of the bolts 18 are threaded to receive the winged nuts 19. Arranged adjacent the bolts 1S are the projections 20 arranged to engage with the wires 17 for the purpose of adding tension to the wires and to prevent to a degree the turning of the bolts 18. The arm of one of the cross-fittings opposed to the arm carrying the frame 14 carries a finger 21 the projecting portion of which is angular. Carried by the finger 21 is a set screw 22 arranged for operation in the slot 23 formed in the arm of the cross-fittings, the slot and set screw acting to limit the movements of the finger 21 in a rotary direction.

24 designates a spring which embraces the fitting having its one end secured to the iitting and its opposite end secured to the set screw.

25 designates a semicylindrical, metallic casing supported beneath the shaft 11 upon the uprights 26 and is secured to the track way 2 by means of the bolts 27. Secured on the inside face of the casing 25 are the curved ribs 23 forming a cam way 29 through which the finger 21 travels for raising and lowering the frames 14. For causing the frames 14 to move lengthwise of the machine in one direction there is arranged on each alternate link of the conveyer a member 30 projecting laterally, which are arranged to engage with a lever 31 carried by the shaft 11 and secured thereto against longitudinal movement by means of the collars 32. The lever 31 is provided with an integral extension 33 arranged for engagement with the outer end of the casing 25 as required to hold the lever in a position engaging with the projection 30. F or moving the frames rearwardly or to their initial positions I have provided the pitman 34 which is connected with the lever 31 at one end and at its opposite end with the lever 35, which lever is pivoted to the track way 4. Connected with the lever 35 is a link 36, the forward end of which carries a downturned projection 37 extended laterally from which is a roller 3S arranged for travel in a guide 39 which is secured to the track way 2, the projection 37 being arranged for engagement with the projections 30. The guide way 39 is so shaped as to elevate the projection 37 out of the path of travel of the projections 30 at times. For carrying the frames 14 in a nonoperative or elevated position, or in other words, to support them while they are returning to their initial positions, I have provided the arm 40 which is carried by one of the frames in a position adjacent the cross-coupling 12, the free end of which arm 40 terminates in a shoe 41 designed for travel upon the resilient track 42 lying adjacent the left hand margin of the casing 25 and being fixed at its forward end to the casing, and, adjacent its free end there is an up-turned, curved portion 43 against which the shoe 41 engages to start the frames to fall into an operative position. At the forward end of the track and secured to the casing 25 is the cam groove 44 which engages the shoe 41 to lift the frames 14 to an inoperative position.

In the practical operation ofthe machine assuming the parts to be in position as shown in Figs. 1 and 3, it is obvious that as the tiling or product of the tile forming machine as it is forced from the tile forming machine will be supplied to the conveyer blocks 9, and as the tile is forced from the machine by its weight and engagement with the conveyer blocks the entire conveyer is moved without extraneous power. By reason of the engagement of the projections 30, carried by the links of the conveyer, with the lever 31 the frames 14 will be moved lengthwise of the machine and at the same rate of speed as the travel of the conveyer. Simultaneously with the moving of the frames 14 lengthwise relative the machine they are brought to a cutting position by means of the finger 21 engaging in the cam groove 29 which, as shown in Fig. 7 is inclined downwardly for a portion of its length and thence upwardly, the downwardly inclined portion serving to move, gradually, the frames 14 and the wires, which perform the cutting, downwardly through the tile, the upwardly inclined portion serving to lift the frames and the cutting wires out of the tile, all of which is accomplished while the tile is moving.

As shown in the drawings, the conveyer blocks are provided with two depressions each and there is provided a pair of frames 14 having cutting wires. By such a machine two tiles may be cut in sections at the same time, this being my preferred form of machine. If only a single tile is to be cut the conveyer blocks are provided with a face to receive one tile only and one of the frames and cutting wires is dispensed with.

After the machine has reached the limit of its cutting movement one of the projections 30 engages the down-turned extension 37 of the link 36 and moves the entire link rearwardly. In moving the link 36 rearwardly through the medium of the lever 35 and pit-man 34, the lever 31 together with Ithe shaft 11 and frames 14 are moved to vthe tile is being continuously formed and discharged from the tile forming machine.

I claim:

1. In a tile cutting table, a frame, endless track ways supported by the frame, an endless conveyer arranged for travel on the track ways, conveyer blocks spaced apart and carried by said conveyer, a shaft carried by the frame lengthwise thereof, a bowshaped frame carried by said shaft, a cutting member carried by said bow-shaped frame, projections arranged at intervals on said conveyer, a lever secured to said shaft arranged for engagement with one of said projections so that as the conveyer is moved the shaft and said bow-shaped frame will move with the conveyer, a finger projecting downwardly from said bow-shaped frame,
